This is a monumental record in the history of rock and roll, from its iconic cover (which the Clash later paid homage to on the cover of London Calling) to the twelve great tracks to its unprecedented sales figures (it topped the billboard album charts for 20 weeks). The RCA material includes Elvis' arrangement of Blue Suede Shoes and covers of r&b hits Money Honey, Tutti Frutti, and I Got a Woman. The record is short (29 minutes) and the material it contains is available on lots of other discs, but if you must have the record that started a revolution, this is the one to get.
